  1. * Data from the animals sampled in this study.
  2. ** Data obtained from the Swiss Federal Office of the Environment [55].
  3. Population size is based on counts and estimates from wildlife managers and biologists.
  4. Mean altitudes differed significantly between species (p < 0.05): Ibex were found higher than all other species (Alps), and chamois were higher than roe deer and red deer (all bioregions).
